s ra'rnn DEODORIZING DEVICE.

Specification of Letters Patent.

Patented May 25, 1915.

Application filed September 29, 1913. Serial No. 792,438.

To all whom it may concern:

Be it known that I, WILLIAM H. SARTAIN, a citizen of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented certain new and useful Improvements in Deodorizing Devices, of which the'following is a specification.

My invention relates to deodorizing devices of the type particularly used in connection with refuse disposal plants, slaughter houses, etc.

More specifically, the provision of a structure for positively preventing the escape of all noxious gases prevalent in establishments of the type referred to, to the atmosphere. Various municipal ordinances prohibit the escape of these noxious odors and Various devices have been provided for complying with them. However, these devices, while bearing in mind that all gases are not condensable or soluble in water, the main effort has been directed to the removal of the condensable or soluble gases or vapors.

My invention, therefore, resides essentially in the provision of a means for positively removing all the noncondensable gases or vapors.

The preferred means for accomplishing this I have illustrated in the accompanying sheet of drawing, in which similar characters of reference designate corresponding parts and in which the figure is a diagrammatic representation of a structure for carrying out the above principle.

In establishments where these noxious odors prevail, rendering tanks are usually provided for rendering out all the salable by-products of the refuse collected. This rendering tank I have shown at l as mounted in any desired manner upon supports 2. The top of this rendering tank is preferably concaved as shown at 3, this concaved portion being formed in this manner to form a receptacle for the refuse prior to its placement within the rendering tank through an opening a operating in any desired manner. Reference to the figure will also indicate that the lower portion of the rendering tank is provided with a well known type of manhole 5 having any preferred type of closure 6 through which the rendered refuse may be withdrawn. The refuse within the tank is heated in any desired manner preferably by the use of steam under a definite pressure my invention resides in introduced through the lower portion by means of the pipe 7 The heat from this steam will render out all the desirable byproducts and at the same time generate a considerable quantity of noxious gases or vapors which will collect in the upper portion of the rendering tank. These gases, together with the steam, after it has performed its function, are allowed to escape through a pipe 8 which leads into a jet condenser 9. Water enters this jet condenser through the pipe 10 and its passage is controlled by means of the regulating valve 11,

this condenser comprising a four-way fitting as shown, the pipe 10 entering from the top. Flowing of this water through the condenser will cause a condensation of all the vapors entering from the rendering tank and will further cause a portion of the gases to enter into solution and pass downwardly into a deodorizing tank 12, which tank is hermetically sealed and is in communication with a sewer through a siphon pipe 13. It will be apparent that all of the noxious gases or vapors combining in any manner with a condensing water, will then be conveyed to an outlet sewer.

After the steam has been allowed to pass through the refuse in the rendering tank for a sufficient time, the man-hole 5 is opened and the residue transferred to a drier 141. This drier is steam jacketed as shown at 15 and is provided with a suitable stirring device, not shown, but mounted upon a shaft 16 carrying the bevel gear 17 at its outer end. This bevel gear 17 is driven through the medium of the bevel pinion 18 carried upon the shaft 19 suitably journaled in vertical standards 20 and driven by a belt 21 passing over a pulley 22 carried thereby. The drier is further provided with an inspection opening 23 which may be manually controlled by being pivotally connected to a lever 2 1 fulcrumed at its end, as shown at 25. Continued stirring of the residue, together with the action of the heat caused by the steam in the steam jacket 15, will cause a further generation of gases and vapors, these being permitted to pass outwardly through the pipe 26 having a controlling valve 27 in circuit therewith. A majority of the gases and vapors generated during the course of operation, occur in the drier and consequently I have provided a much larger pipe to convey these gases away than that employed in connection with the rendering tank. The gases leaving the drier are also caused to enter the condenser 9 at a point opposite the entrance of the pipe 8, and a similar action occurs as has been previously related.

As stated, not all of the gases thus generated are condensable or soluble in water and as a result, a considerable quantity of these are collected in that portion of the deodorizing tank above the level of the outlet pipe 13. Inasmuch as these gases and vapors are usually of a noxious variety, they must be withdrawn in a manner that the surrounding atmosphere is not contaminated. This I accomplish by providing the upper portion of the deodorizing tank with an outlet pipe 28 leading to a suction fan 29, this fan carrying a pulley 30 and being driven from any suitable source of power by means of the belt 31. Inasmuch as the non-condensable and non-soluble vapors form a small percentage of the whole, this fan may consequently be of a somewhat small capacity, it being large enough only to Withdraw this small percentage of gases and convey them to the fire box or smoke stack of the boiler furnace through the pipe 32. It will thus be seen that all of the gases emitted from the refuse placed within the rendering tank, are conveyed in some manner to the deodorizing tank 12 similarly to the gases emitted from the residue within the drier 14. These gases are all caused to pass through the jet condenser 9 where a greater portion of them enter into solution with the condenser water and pass out- G'opies of this patent may be obtained for five cents each, by addressing the wardly through the pipe 13. The remaining gases or vapors are positively withdrawn and passed outwardly to the furnace by means of the suction fan 29. After the operation of the drier upon the residue placed therein from the rendering tank, the remaining product is what is generally termed as a fertilizer.

What I claim, is: 1. In a refuse disposal apparatus, a rendering tank, a drier, a jet condenser, outlet pipes from both said rendering. tank and said drier leading to said condenser, an air tight tank in communication with said condenser, awater outlet pipe for said air tight tank, and a suctionfan in communication With the upper portion of said air tight tank independent of said condenser.

'2. In a refuse disposal apparatus, arendering tank, a drier, a fouravayfitting, outlet pipes from both said rendering tank and said drier leading to said fitting, a water inlet pipe leading into the upper portion of said fitting, an air tight tank forming the fourth connection with said fitting, a Water outlet pipe for said air tight tank, and a suction the upper portion of said air tight tank independent of the connection with'said fitting. a
